I have a strange problem with my Sony C1VFK Picturebook; sound is sometimes working, and sometimes not. Eg when I booted this morning I got the usual tune while logging in, but when I tried to use RealPlayer just now (with a file I had heard before) the sound had disappeared. I don't know if this is a software or hardware problem? Does sound hardware ever work sporadically like this? The sound system is Yamaha YMF-754 [DS-1E Audio Controller]. I'm using the snd_ymfpci module. I'm running Fedora-4. I've tried a few kernels, official and compiled, and they all seem to show the same behaviout. Incidentally, I am slightly puzzled by the fact that the module is sometimes called snd_ymfpci and sometimes snd-ymfpci . Eg with linux-2.6.12-1.1398_FC4 lsmod lists snd_ymfpci while the relevant module is /lib/modules/2.6.12-1.1398_FC4/kernel/sound/pci/ymfpci/snd-ymfpci.ko . Is there some mechanism for translating the "-" into "_" ? -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
